These results certainly depict the chances of degradation of ecological sustainability which has also been observed using a land use-based Composite Ecological Sustainability Index (LUCESI). Use of different landscape metrics like Percentage of Landscape (PLAND), Largest Patch Index (LPI), Number of patches (NP) and Mean Euclidean Nearest Neighbour Distance (ENN_MN) within a fishnet grid space of 1 km × 1 km dimension reveals the areal extension and connectivity between vegetative landscape and water bodies has decreased with a steady increase of fragmentation until 2010, whereas the situation is completely reversed for builtscapes, especially in Action Areas I, II and III of New Town Rajarhat. Computation of Landsat 5 TM and Landsat 8 OLI images for the years 1988, 2000, 20 reveals that there has been a steady growth in urban environment (1.35%/year) at a cost of altering natural resources. This study tries to investigate the spatio-temporal dynamics of land transformation patterns coupled with a holistic apprehension of landscape sustainability induced by different facets of ecological configurations of different land utilization, applying modern-day’s techniques from geospatial platform and landscape metrics within a multi-criteria framework of Analytical Hierarchy Process (AHP) in one of the new town project areas of Easter India. It immediately needs cost-effective monitoring and evaluates the policy for ecological sustainability. The uncontrolled growth of urban population in developing nations has led to a situation of rapid alterations of peri-urban land.
